  • each of the jackwires in the prior art of Figure 4 must be made robust in the less conductive area 43 using the additional layer 45.
  • the Applicant has discover a way to make a jack which will perform to suppress damage from sparks and arcs during a decoupling of the plug from the jack, while sparing the cost of coating a portion of each of the jackwires with the layer 45. In other words, by controlling at least part of the order in which the jackwires disconnect from the blades of the plug, several of the jackwires do not need to have the additional layer 45.
  • An upgraded RJ45 jack is the best solution for new, future products to reduce damage from PoE sparks.
  • An upgraded RJ45 jack can also offer some limited benefits as a retrofit solution for existing networks.
  • Replacing the RJ45 communication jack 20 within a wall plate 18 (of Figure 1) is not entirely difficult. However, it does take time for a trained technician to cut the communication jack 20 free from the twisted pair cabling 26 within the wall, and install an improved communication jack with enhanced jack wires. Upgrading the communication jack within a device, e.g. the portable hard drive 10, is much more difficult. The housing or casing of the device must be opened, and often times the communication jack is soldered onto a printed circuit board within the device. Hence, replacing the communication jack of a device is extremely time consuming and runs the risk of damaging the device.
